AQUAD 8 is available in revised version as free and open source software under the terms of the GNU General Public License v3 in four modules for the analysis of texts, audio recordings, videos and graphical materials.
The previous version 7 was revised with LAZARUS 2.0.10 / FPC version 3.2.0. Results are shown in the Windows version with "notepad.exe", copied, printed, etc. Numerical results are stored in CSV tables.
The separate module aquad_eda.exe is installed automatically. It contains revised scripts for exploratory data analysis with "R", Version 4.0.2. It comes with scripts for distribution description, correlation calculation, data plots, cluster analysis, multidimensional scaling and determination of prototypes.
With AQUAD 8 you can process these data types with the following modules:
Texts (*.txt; e.g. transcriptions of interviews, letters, documents) in aquad_8d.exe, Audios (*.mp3, *.wav, *.aac, etc.; e.g. interviews, radio transmissions) in aquad_8d_audio.exe, Videos (*.mp4; *.avi, *.mov, etc.; e.g. observations, movies) in aquad_8d_video.exe and Images (*.jpg, *.png; e.g. fotos, drawings) in aquad_8d_grafik.exe
To use all functions, both the free software "R" (download from and the free media player "VLC" (32-bit ! download from must be installed on the computer.
A manual is in preparation. Since the basic principles have not been changed the manual of version 7 can help for the time being. AQUAD 7 is still available for download as free software according to the terms of the GNU General Public License v3 for download.
